Texto completoMaize stands as a pillar of the French forage system, with its yield and silage feeding value serving as key criteria for the registration of maize hybrid varieties in the official French catalogue. Previous research on this topic has revealed a direct correlation between silage feeding value and dry matter (DM) digestibility, which is, in turn, constrained by cell wall (CW) digestibility and significantly affected by water deficit. Studies on maize inbred lines have shown that under severe water deficit conditions, both DM and CW digestibilities increase. This increase correlates with a decrease in lignin content and changes in lignin distribution. However, it is noteworthy that breeding efforts have already fixed lignin content in hybrid varieties. Therefore, lignin content is unlikely to be a source of future digestibility improvement. To explore other CW targets and the impact of water deficit on these traits, this PhD study was conducted as part of the Carnot Plant2Pro INRAE-ARVALIS MAMMA MIA project. We grew a range of modern forage maize hybrids representative of the current S0-S1 (very-early to early flowering earliness) French market for two years under sixteen contrasted environmental conditions, including six in controlled irrigation conditions. First, we established a simple but robust stress index (SID) that considers the water deficit in the soil and the air temperature. This SID provided a key environmental ranking tool, highlighting severe stress due to high temperature that significantly impacted DM digestibility compared to moderate stress conditions. Secondly, to encompass a wide range of environmental conditions in biochemical quantifications, we developed several predictive near-infrared spectroscopy (NIRS) equations capable of robustly and accurately predicting fine cell wall traits and relationships, mirroring levels observed in laboratory experiments. While these equations prove sufficiently robust for use in selection programs, we emphasize the need for vigilance in accurately estimating prediction accuracy under stress conditions, particularly in equations applied to hybrid material where trait variation ranges are often limited. The core dataset of this work enabled a multiscale analysis, integrating agroclimatic, agronomic, biochemical, and histological traits, along with in sacco experimental data on cows. We proposed biochemical and histological traits to improve the quality of forage maize depending on stress intensity. We demonstrated that under severe stress, ear production decreases significantly, but DM digestibility can be maintained by increasing CW digestibility. This boost in CW digestibility was due to a reduction in p-hydroxycinnamic acid content, while lignin content remained stable, as anticipated. The significance of lignin distribution increased with the severity of stress, reaching an extreme threshold where biochemical parameters solely account for digestibility variations. This two-threshold model presents a window of opportunity located at the first threshold between non-stressed and moderately stressed environments, where the increased role of lignin distribution alongside biochemical traits enabled an increase in digestible yield. By controlling irrigation doses in the field under moderate drought conditions and integrating the SID into an irrigation management tool, farmers could exploit this window to increase productivity

Texto completoThis thesis aims at investigating an alternative MultiCarrier Modulation (MCM) scheme, named OFDM Offset QAM (OFDM/OQAM), in the Power Line Communications (PLC) context. The objective of this thesis is to illustrate the pros and cons of the OFDM/OQAM compared with the widely used OFDM scheme and further demonstrate the feasibility of using OFDM/OQAM in PLC. The main contributions of this thesis include: 1) PLC channel analysis: we analyze the PLC channel from an information theory point of view; 2) Analytical transmission model: we derive a theoretical transmission model for the OFDM/OQAM system over frequency selective channel; 3) Prototype filter design criteria discussion: different criteria of prototype filter design are discussed in this thesis for PLC; 4) Channel equalization methods: we present two channel equalization methods in this thesis and the efficiency of the presented methods is evaluated by simulations; 5) Capacity analysis: the transmission capacities of the OFDM and the OFDM/OQAM are analyzed/compared in this thesis and the fact that, under the most recent HomePlug AV specifications, the OFDM/OQAM system can, generally, provide higher capacity than the one of OFDM system is shown; 6) Flexibility: we point out two flexibilities in the PLC contex

Texto completoThe research presented in this thesis focuses firstly on the reliability of PLC technology and secondly on the diagnosis of wired networks using PLC in the aeronautical sector. First of all, we studied the OFDM synchronization in a PLC communication chain for data transmission on avionic systems. The objective of the study is to make the PLC link more reliable by respecting the latency constraints set in the aeronautical domain. We introduced sampling frequency errors in order to analyze the effects of sampling frequency desynchronization on the bit error rate. We then proposed an optimized algorithm for error estimation. The second contribution of the thesis is devoted to the monitoring of embedded wired networks and the objective being to use PLC communication as a mean of detecting a fault. We focused our study on the detection of a fault following an electric arc, modeled by a parallel resistance, or a connection fault, modeled by a series resistance on a wire of the two-wired cable. In order to have the channel characteristics with and without faults, a test bench of a multi-branch harness has been designed with different resistive fault samples. We proposed several correlation-based fault detection coefficients, Euclidean distance, and a blind algorithm based on received symbols. In order to avoid false alarms or no detection, detection thresholds were discussed. The different detection coefficients and the thresholds were compared and tested in the presence of white noise in terms of the transmitted power and the detection rate

Texto completoThe automotive industry use more and more electronic for comfort, for the security,. . . However, the manufacturers observed a bottleneck in wiring harnesses. We propose to study a new communication network which does not need new wires: the power line communication (PLC). In a first step, we realized a study of feasibilty with indoor modem (HPAV & HD-PLC standard). Then, we studied and characterized the in-vehicle PLC channel thanks to measurements on four vehicles. Afterwards, a study (simulations) on the parameters of a multicarrier modulation showed that we can increase the inter-carrier spacing and reduce the guard intervall length compared with HPAV. Finally, we realized a flexible demonstrator which use a software-defined radio platform USRP2. The first results are similar with the simulations

Texto completoLignocellulosic biorefineries are rapidely developing as they offer alternatives to petroleum industries’s products. Lignin, one of the three main constituent of plant cell, is hardly valorized due to its complex and diversified structure. This biopolymer, made of polyphenols, is the largest natural and renewable resource of aromatic molecules. Many researches aim at functionalizing lignin in order to improve its properties. Most of lignin modifications have the disadvantage of generating salts and by-products in stoichiometric amounts. Cleaner functionalization methods are consequently needed. This thesis manuscript presents new catalytic grafting methods based on the use of butadiene, carbon monoxide and allylic alcohol as clean, efficient and economic alkylation/acylation reagents. These functionalizations have a significant impact on the physicochemical properties of lignin. In addition, the presence of new unsaturations in the material opens the way to further functionalization and crosslinking pathways
